  bibo_abstract:
  - A rapidly increasing body of work reporting phenomena associated with lattice
    vibrations carrying angular momentum has led to the emergence of the field of
    chiral phonons. Some of these properties, such as the phonon magnetic moment,
    also occur in achiral phonons that are circularly or elliptically polarized, while
    the presence of chirality has additional implications for the types of interaction
    allowed between the phonons and light, electrons and other quasiparticles. In
    this Perspective we introduce a framework for classifying phonons with angular
    momentum, and provide illustrations of the different types using examples from
    the recent literature. Specifically, we suggest the term ‘axial phonon’ to encompass
    all phonons that carry angular momentum, real or pseudo, and reserve the term
    ‘chiral phonon’ for those phonons that break improper rotational symmetry. We
    hope that this scheme provides clarification on the matter of phonon chirality
    and will serve as a guide for future research.@eng
